Be it known that I, Grouse T. STEWART, e citizen of the United Stades.3 residing et Larruhee, in the county oi Cherokee und State of lows, have invented cer-taie new aud useful lmprovemeuts ir. tecla-latering Troughs; and l do hereby declare the oilouirigrto be :i full, cleetr7 und erect description of the invention, such as will enable others skilled in the art to which it appertaius to Hieke und use the serle.

This invention relates to troughs und more perticuierl Y to e stock Wetering trough designed for Wetering; hogs and the hire.

rlhe principal object of the invention is to provide s Wetering; trough embodying a trough casing in which is arranged e, Watering trough in spaced relation to the bottom and side Walls of the trough casing so as to provide uu air space surrounding the trough, und if desirable e hosting medium muy he arranged Within this air spece whereby the contents of `the Watering trough muy he kept sufficiently Wurm to prevent it from freezing in cold Weatherz Another object ot' the invention is the provision ot' a Watering trough of the above stated character hui eplurelity of pertitious positioned between the trough aud Vtrough casing iu such u manner as to provide u circuitous passage extending from the heating medium forwardly and beckwilrdly arouudseid trough then exhaustrg through s suitable vent opening formed :i the trough casing.

'further object of the invention is to provide e, outer supply taulr which is courecited to the Wetering trough tl'lrough the ediuri of e suitable pipe, un automatic cut p13 vulve being' arranged Within the trough und connected to the terminal end o the suoolv pipe? said `vulve serviugin conjunctioii fr/ith the Water pressure of the supply tenir to keep tl is Wetering; trough filled with supply of Wut Still further of the invention is 'volvo adapted to be ough is full of i ot the huoyuucy ire. of the 'Water Specicaten of Letters Patent.

from the supply tank, seid valve opening es the Water is taken from the trough, thus allowing the Witter to flow into the tank to s predetermined level whereupon the valve will be again closed.

A still further object of the invention is to surround the Water supply pipe With u hot air exhaust pipe, which has one end etteclied to the trough casino; over the vent opening1 thereof und the opposite end of 'the exhaust pipe terminating :it e point adjacent the water supply tank, whereby the hot air es it is exhausted from the Wetering trough will circulate around the Witter supply pipe und exhaust beneath the supply tenir, thus providing u menus to prevent the water in the supply pipe und supply tank from freezing in cold Weather.

lVith these und other objects in View, es will appear as the description proceeds', the invention comprises the various novel features or" construction, combination and ur rangement of parts :is will be more ull described hereinafter and set forth Wit particularity in the appended claim.

Referring to the drawings,

Figure l is a perspective View of my improved stock Wetering trough with e Water supply tank connected thereto.

Fig. 2 is a vertical longitudinal sectional view,through the Watering trough showing my preferred :t'orm with s heating medium arranged therein.

Fig. 3 is u sectional plan View taken on the line 3 3 of Fig. 2.

Fig. l is e vertical transverse sectional View teken on the line 4-4 of Fig. 2.

Fig. 5 is a vertical transverse sectional View teken outlieline 5-5 of Fig. 2.

Fig. 6 is e rugmentary vertical sectional View taken ou the sume line as Fig. 5.

Fig. 'Z' is e vertical longitudinal sectional View of another form of watering trough, the outer casing being removed and showing the supply pipe extendingl iu from the upper rear end of the trough.

Fig. 8 is another form of trough showing the supply pipe extending in from the top or the trough.

Fig. 9 is e fragmentary vertical longitudi- Leanser stance is arranged in a position Slightly above the watering trough So as to produce the desired pressure within the supply pipe. A hot air exhaust pipe 43 surroundsthe supply pipe 3l and has one end attached to the side Wall orerthe rent opening 1T,and the opposite end of the hot air exhaust pipe terminates at a point` adjacent the supply tank .i-L. Freni thisI arrangement it will be apparent that as th; hot air is exhausted Ithrough the vent opening l? it will pass outwardly through the exhaust pipe #L3 around the supply pipe 3l and exhaust immediately beneath the supply tank 42, this heated air crying to prevent water in the tank and the suppiy pipe 3l from freezing in cold weather.

In the operation oi' the device the Water will fion' troni the supply tank 42 through the supply pipe 3l inte the watering trough i() through. the valve arranged therein, until, me water has reached a predetermined height or lerel'whereupon the buoyancy of the the tio.

'-.rater lfreni the supply tank will iloat VS upn'ardlv and more the salve 'o engagement with the valve seat as shut oit the supply et Water the wa. in the trough has reached Lerinined level. As the water the trough. the heat 2G will ne o des fl, in rien' o the 'act that i tank the. p1 i der in the ipp is nou finito t te hold the. ia ve 3S up 'ag-eins therefore water wil aen. f" nk until it has reached provided with a connected thereto at .lly the saine construc- 'icing also provided plate 7. In this is extended into the thc rear end 4S cover 'faire arran Terr ent conne i with 'ticniarly shown iere'ore 'the saine 5e For this Jforni ther forni shown in as the he supply i ep Z of the :di the saine kind as heretofore dethe dr Wings therewater in lconnection with the pressure oi'- saine reference numerals will sufnr a description ot this torni of valve. The taire rod in this instance is pirottra extending s attached to theunderneath surface )at 2G. `rlhe hinge ineniner 39 is pivot mounted upon a hinge rod 39 that ds transversely or and 1s secured to the nails of the trough. As the i'ioat 26 is ed upwardly under the buoyancy of the Lier, the extension Se will nieve downwa. li.' pulling the Valve rod 39 aise downnf'; 1y thus closing the valve 'from a further admission of water into the tank. rEhis ffrin of tank also has the outer casing as dead air space provided with a inediuni is not necessary.

. Wiii be seen a stili furthe f niodi of iny invention, in which the trough is inade o't wood, like the in 7? and is provided with a sightilg. ditercr construction ot' tleat valve7 out embodying the saine principie. rEhe supply -)ipe 3l in this instance extends in through the rear end 4) ot' the trough and at the bottoni portion thereof and is securely attached to the end through the Ine- .fiiuin or' retaining nuts 50.

The inner end of the supply pipe 31 is threadedly connected as at 5l to one end of an angular valve casing,` that is secured to the bottoni i3 by screws 5a or other suitahle fastening means. Sie shown this valve easing is provided With an upwardly 'eX- tending portion and is internally threaded to receive a valve plug 56 which is iden tical in construction with the Valve plug hereinhctrn'e described. This plug is provided with a valve seat, 57 against which rests the hall valve 58 which may he of ruhher or any desired construction and is attached to the valve rod 59, said 1Jalve rod e5;tending; upwardly and attached to a Suitahle ioat 6G disposed in the upper portion ot' the trough. The action of this Valve is identical. with those before described, vtherefore it not thought necessary to lgive ay detail description thereta.
